Minikube will not start again after a stop

Question

Running gentoo linux... I am new to kubernetes and learning it on my dev cloud. I am able to start minikube with no issues (other than the second node is missing...not sure why). Then I stop minikube. When I start it again it will not start with GUEST_PROVISION_CONTAINER_EXITED. I have to reboot my server to resolve it.

Anyone know how to fix this?

â  Exiting due to GUEST_PROVISION_CONTAINER_EXITED: Docker container exited prematurely after it was created, consider investigating Docker's performance/health.

Answer 1

This is generic docker debugging help. I've installed minikube, but haven't ran into this particular inconvenience.

When it says "consider investigating Docker's performance/health" it probably means to check the docker logs

docker ps --all

should give you a list of images, if this is your only docker project, then it oughta be easier to find. The 3rd column in that list is the container_name parameter you want to feed to docker logs [container_name]

Whatever caused your container to stop prematurely ought to be in there.

Assuming you're running a production build of minikube, the chances are good it's something with your setup, probably filesystem related, but who can tell until you debug it.
